Airbrush Compressor: help me decide!

Posted in Custom Workstation

Hi!
I need an airbrush compressor to start doing some paint jobs and was able to find 2 on e3ay.co.uk (since I'm in Europe).
One is a diaphragm membrane compressor and the other one a piston compressor.
They both cost the same, but which one should I choose??
Diaphragm is item number 290422243791
Piston is item number 300416664017

Please help me out!
